DIET-PC (DIskless Embedded Technology Personal Computer) is a software kit enabling IT professionals to build embedded Linux appliances based on commodity PC or Mac hardware and various commercial embedded appliances. The focus is on platform portability, OS fundamentals and developer friendliness, rather than the end-user UI. The distribution is intended primarily for desktop graphical appliances, particularly thin clients (using the X11/XDMCP, ICA, RDP, and RFB graphics protocols). Although originally a network-booting OS, DIET-PC works well with various forms of solid-state persistent storage and hence is no longer strictly "diskless". The project uses QEMU virtual machines running Debian Linux (under Windows) as self-contained development environments, and hence may also be of interest for its unusual (non-x86) QEMU accomplishments.
